What is zero divided by zero anyway?

I have always thought that there are three possible answers to the question what is 0 / 0:

- zero, since zero divided by anything is still zero;
- infinity, since anything divided by zero is infinity;
- one, since anything divided by itself is one.

Of course my thinking can be very wrong as zero is not just *anything* -- it is a special case in itself. 0 / 0 *may* be equal to zero, one and infinity at the same time, but it is probably easier to say that it is undefined. Or even Mu.
